PET/CT Scan, Skull Base to Mid-Thigh

Illinois rates for HCPCS 78815

A scan that combines PET, which shows how active tissue is after an injection of a radioactive sugar tracer, with a CT taken in the same session to pin down exactly where that activity sits. It covers the body from the base of the skull down to the middle of the thighs, the region examined in most cancer staging and follow-up. You fast beforehand, rest quietly while the tracer is taken up, then spend around half an hour in the scanner.
